A novel maize variety designated X90P469 and seed, plants and plant parts thereof are produced by crossing inbred maize varieties. Methods for producing a maize plant by crossing hybrid maize variety X90P469 with another maize plant are disclosed. Methods for producing a maize plant containing in its genetic material one or more traits introgressed into X90P469 through backcrossing or genetic transformation, and to the maize seed, plant and plant part produced thereby are described. Maize variety X90P469, the seed, the plant produced from the seed, and variants, mutants, and minor modifications of maize variety X90P469 are provided. Methods for producing maize varieties derived from maize variety X90P469 and methods of using maize variety X90P469 are disclosed.
A seed of hybrid maize variety X90P469, representative seed produced by crossing a first plant of variety PH2TBY with a second plant of variety PH4DFJ, wherein representative seed of the varieties PH2TBY and PH4DFJ have been deposited under ATCC Accession Number PTA-124775 and NCMA Accession Number 202204012 respectively.
A seed of hybrid maize variety X90P469 further comprising a single locus conversion, wherein a plant grown from the seed comprises a trait conferred by the single locus conversion, and wherein the seed is produced by crossing a first plant of variety PH2TBY with a second plant of variety PH4DFJ, wherein the first plant, the second plant or both further comprise the single locus conversion, and wherein representative seed of the varieties PH2TBY and PH4DFJ have been deposited under ATCC Accession Number PTA-124775 and NCMA Accession Number 202204012 respectively, and wherein the seed produces a plant having otherwise all the physiological and morphological characteristics of maize variety X90P469 when grown under the same environmental conditions.
A method for producing a hybrid maize variety X90P469 seed further comprising a locus conversion, the method comprising crossing a first plant of variety PH2TBY with a second plant of variety PH4DFJ, representative seed of the varieties PH2TBY and PH4DFJ having been deposited under ATCC Accession Number PTA-124775 and NCMA Accession Number 202204012, respectively, wherein at least one of the varieties PH2TBY and PH4DFJ further comprises the locus conversion.

The goal of hybrid development is to combine, in a single hybrid, various desirable traits. For field crops, these traits may include resistance to diseases and insects, resistance to heat and drought, reducing the time to crop maturity, greater yield, and better agronomic quality. With mechanical harvesting of many crops, uniformity of plant characteristics such as germination, stand establishment, growth rate, maturity, and plant and ear height is important. Traditional plant breeding is an important tool in developing new and improved commercial crops.
Provided is a novel maize, Zea mays L., variety, seed, plant, cells and its parts designated as X90P469, produced by crossing two maize inbred varieties. The hybrid maize variety X90P469, the seed, the plant and its parts produced from the seed, and variants, mutants and minor modifications of maize X90P469 are provided. Processes are provided for making a maize plant containing in its genetic material one or more traits introgressed into X90P469 through locus conversion, backcrossing and/or transformation, and to the maize seed, plant and plant parts produced thereby. Methods for producing maize varieties derived from hybrid maize variety X90P469 are also provided. Also provided are maize plants having all the physiological and morphological characteristics of the hybrid maize variety X90P469.
The hybrid maize plant may further comprise a cytoplasmic or nuclear factor capable of conferring male sterility or otherwise preventing self-pollination, such as by self-incompatibility. Parts of the maize plants disclosed herein are also provided, for example, pollen obtained from a hybrid plant and an ovule of the hybrid plant. Seed of the hybrid maize variety X90P469 is provided and may be provided as a population of maize seed of the variety designated X90P469.
A new and distinctive maize hybrid variety designated X90P469, which has been the result of years of careful breeding and selection in a comprehensive maize breeding program is provided.
Maize, Zea mays L., can be referred to as maize or corn. Certain definitions used in the specification are provided below. Also in the examples that follow, a number of terms are used herein. In order to provide a clear and consistent understanding of the specification and claims, including the scope to be given such terms, the following definitions are provided. NOTE: ABS is in absolute terms and % MN is percent of the mean for the experiments in which the inbred or hybrid was grown. PCT designates that the trait is calculated as a percentage. % NOT designates the percentage of plants that did not exhibit a trait. For example, STKLDG % NOT is the percentage of plants in a plot that were not stalk lodged. These designators will follow the descriptors to denote how the values are to be interpreted. Below are the descriptors used in the data tables included herein.
BRITTLE STALK: A count of the number of “snapped” plants per plot following machine snapping or artificial selection pressure. A snapped plant has its stalk completely snapped at a node between the base of the plant and the node above the ear. Can be expressed as percent of plants that did not snap.
